OK, so the Protank 2 coils were a real PITA to test.
The 40gauge thermocouples are tiny, delicate, and they fell out easily and frequently. So I got a chance to see and feel the wicks a lot while re-threading the probe. There is no doubt, the rebuilt coils with cotton held magnitudes more juice than the stock coils with silica wicks.
This may shock some tootle folks, but data is data, and this is what I measured.
Stock 2.2 ohm coil on a Protank2. Red was 5.5w, yellow was 5.0w, and blue was 6.0w
************************************
YES: On a Protank 2 with a stock 2.2ohm coil
you are hitting over 500F at 6 watts!
************************************
The rebuilt coil made with 30g kanthal and cotton wicks fared much better.
And finally, the full data:
Just for the record, NONE of these hits tasted burnt!
Properly rebuilt coils are pretty safe temp wise, stock silica coils are NOT, at least according to Wang and Geiss.
